JAWS Motorsport's E60 M5 hits 518 horsepower to the wheels and 8600 RPM on the S85 V10 with their Alpha-N tune

Impressive naturally aspirated and stock internal work here on the S85 V10 by BimmerBoost vendor JAWS Motorsport. The car put down a baseline of 448 wheel horsepower on a DynoMite dyno with just intake scoops. From that baseline JAWS was able to hit 518 wheel horsepower with addition of their one piece plenum, Alpha-N tune with 8600 RPM limiter, and secondary cat delete. That is a gain of 70 horsepower at the wheels.

Keep in mind that this was done on pump fuel with the stock exhaust (other than secondary cat delete) and stock headers. Is there more to be gained here? Absolutely and we expect an update as JAWS revises their tune with their headers that are being finished up. We have no idea how much more they will hit but the results so far are definitely impressive and this is one of the strongest naturally aspirated S85's we have seen. Pictures, graphs, and video below.

Still not as good as S85. What bothers me is that BMW took S85 design and made it better with S65. Much better headers, exhaust, tune but after all, the 100hp/liter ratio only raised to 103.5hp/liter! Your car is very sick man. Did you use stock DME or went fully standalone?

The hp per liter and torque per liter numbers don't point to it being all that much better. Wasn't the s85 dry sump too? All they really improved were the headers which they needed to due to the displacement loss and they improved the knock detection.

What is the accepted drive train loss on this platform. Does this car have the smg gearbox?

Mostly %17-18 on DJ. The car does have SMG gearbox like all the other non-US E60 M5's.

Exactly my words. Look at S85, with SS headers you gain 50hp. But on S65, SS said it's close to zero. Only M24 claimed a 20hp gain which isn't proven yet. So it means the difference between S65 and S85 should be bigger than 3.5hp more per liter, but it isn't...

We have said approx $4k , but we need to sit down and do a real overlook, its many hours of work on it, and it seems like many want it now so interested better send us an email and put theire name on the que.
